Blasting abrasive white fused alumina price
White fused alumina is made from high quality alumina by being melted above 2000°C in the electric arc furnace. It is characterized by high purity, great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat and high efficiency. White fused alumina can be made into all kinds of abrasives, suitable for grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives; it can be also used for precision casting and high-refractory materials.

1. High hardness, particle density, good circular single particles.
2. The pure white color, without impurities, guarantee the wear-resisting layer or wear-resisting
paper colour and lustre and transparency.
3. The particle size distribution uniform concentration, single particle shape, with the least
amount of biggest wear-resisting effect.
4. It is selected commit suicide by hanging oneself more than two thousand degrees high temperature
melting of high quality white corundum as raw material, made of fine, white corundum its stable chemical properties do not interact with acid, alkali, with low thermal shrinkage.
Application
1)The abrasive tools made by WA are suitable for grinding high-carbon steel, high-speed steel and chilled steel, etc. In addition, it can be also used for polishing materials, precision casting sand, spraying materials, chemical catalyst carrier, special ceramics and high-grade refractories, etc.
2)As coating abrasive grains, White Aluminium Oxide features very strong anti-erosion and grinding ability. Because its grains are sharpened and multangular, there is no clogging situation when grinding. It is suitable for sanding all kinds of soft material, such as wood, plastic, etc.
3)The White Aluminium Oxide also has excellent character in static electricity fields.
